Stag 3GL upper

Stag had a sale on this upper and I scarfed it up quick. I have a Stag 16” carbine but wanted something a little better for coyotes. My lower already has a Geissele SSA-E trigger so this was all I needed to make me a nice small varmit rifle. First time out with it using 55gr factory ammo produced 5 shot groups at 1” at 100 yd indoor range. That’s plenty good for my purposes. Absolutely love Stag Arms rifles!!!

3GL barrel

Excellent fit and finish. Great accuracy and now I have 2 stage 3GL to compete with. Couldn't ask for a better barrel with it's accuracy for the price.

Good Barrel

I have had this barrel for about two years with about 2k rounds out of it. It consistently shoots 1.25 MOA at 200 meters and usually shoots touching groups at a 100 meters and under. I have had zero reliability issues with this barrel utilizing a Superlative Arms adjustable gas block. The machine work was good and I am happy with this purchase. The only thing I would change is I would upgrade it to 416 stainless instead of 410, this is mainly for longevity. But most people wont shoot enough to see this difference. Some people worry about "stingers" with 410 Stainless but I have not had that problem with this barrel. It has been fired in 110 degree 100% humidity in Georgia, and 10 degrees with 20% humidity in Kansas and I have never had a problem with it. It is a little bit heavier than the Faxon and the Ballistic Advantage but the price is also cheaper. You will not go wrong with this barrel for competition or hunting. I also have a Stag bolt that I use with this barrel.
